Introduction Dr. John Holbrook is a professor in the TCU Geology Department. Dr. Holbrook’s current research emphasis revolves around the Fulcrum Theory, a set of calculations that determine sediment discharge of a stream. This measure allows one to estimate and more accurately quantify fluvial sand reservoir rock, which can contain oil and natural gas deposits. Prior to the conception of this project, in order to utilize the Fulcrum Theory, a scientist would need to reach out to Dr. Holbrook who would send an Excel document containing the equations necessary to evaluate the data. This was cumbersome and time consuming. To this end, our research, in collaboration with the Geology Department, focused on creating an user friendly application that would make the Fulcrum Theory more accessible across the world.
Problem Overview • There is no pre-existing application that easily performs the calculations of the Fulcrum
Theory, since it is a newly theorized research method
• The Fulcrum Theory calculations are currently reliant on a default value for the yearly averaged bankfull flow duration (tbd ), a measure of the average number of days a year the river flows at full capacity
• There is no readily available consolidation of river stream data from across the world which is necessary to produce a calculated tbd value based on specific rivers’ attributes
Goals • Provide a user with the option to choose from three different modules, including
Fulcrum Transport Estimate, Stream Specific Bankfull Duration (tbd) Calculation, and River Analogues Search
• Input data into the Fulcrum Theory calculations and return values concerning sediment discharge of a stream
• Determine and return a calculated yearly averaged bankfull flow duration value (tbd) binned on a combination of river stream attributes which can then also be implemented in the Fulcrum Theory calculations
• Display stream data that contributed to the calculated yearly averaged bankfull flow duration value (tbd) to give a user confidence in the calculations
• Enable the user to look for specific analogue streams binned on a combination of river stream attributes
Solution Design A web-based application supported by a database containing consolidated geological stream data enabling easy access and intuitive design for users
The three main components: • Front end: An intuitive User Interface where users can input geological data and receive
calculated values and streams used in the calculations
• Middleware: The bridge between the User Interface and the database performing calculations and facilitating the passing of information between the other two components
• Back end: The database with all relevant stream data loaded and a schema allowing for straightforward queries
System Architecture
Results and Conclusions • Created a full-stack web application supported by a database, currently being
extensively tested
• Calculated a stream specific tbd value, increasing the accuracy of the returned values from the Fulcrum Theory by an order of magnitude
• Created an intuitive User Interface enabling geologists to quickly and efficiently input data and receive results
• Allowed users to download a CSV file of all discharge data for a specific stream
• Included functionality to view analogue streams used in stream specific tbd value calculations
Acknowledgments The RAFTER software development team would like to express our gratitude to Nicole Wilson and Dr. John Holbrook of the TCU Geology Department for presenting us with this challenging, yet rewarding project. We would also like to thank Dr. Lisa Ball for her guidance and constant support throughout the duration of development, as well as the Department of Computer Science for their contributions to our education throughout our years in the Computer Science program.
